Tips on how to clean a waffle iron: After every few uses, when oil collects in the grid, use a bit of paper towel wrapped around the pointy end of a chopstick or a pencil to wipe away the oil and residue within the grid. To remove stubborn, baked-on batter drips, pour a few drops of cooking oil onto the batter. Let it sit a few minutes to soften, then wipe it away with a damp cloth or paper towel.
wish I knew this years ago- Right after using the grill, unplug it and place a wet double-sheet of paper towel between the lid and the surface. The leftover heat causes the towel to steam and clean the grill. Wiping it dry with another paper towel is all that’s needed. I'm going to try with waffle iron.
